Please note: Digistump LLC is NOT currently accepting orders. We are taking a hiatus while we change fulfillment locations and focus on delivering our newest project - BuildOne - The $99 3D Printer. We are also temporarily sold out of Digisparks (over 50k sold!). We will return to normal operations and restock in the first quarter of the New Year. Thank you for your continued support!

Four outputs
Control convection fans and heater elements individually.
Better heat distribution
Having control over individual heating elements allows you to keep heat away from sensitive components.
Hot-spot elimination
Intelligent software manages element on-time, reducing hot and cold spots in the oven.
Better heat direction
Intelligent software controls whether heat comes from the top or bottom, depending on the reflow phase
Better current management
Elements are turned on and off independently eliminating the current spikes common in single-relay controllers
Ready-to-run
No programming needed. Just configure the fans/elements your oven has and the reflow wizard will do the rest. No need to connect ControLeo2 to a computer or write any software!
Proven hardware
ControLeo2 is based on the original ControLeo, which has been field tested for more than a year. ControLeo was based on the Arduino Leonardo - another proven design.
Open-source
ControLeo2 is fully compatible with the Arduino programming environment, and runs Arduino Leonardo sketches. A library and 15 sample programs for ControLeo2 has been posted to GitHub.
Reflow Wizard
Intelligent software makes it easy to get your oven up and running. Ensures consistent results, run after run.
Reflow feedback
If you connect ControLeo2 to a computer you can track the reflow progress and get data to plot a reflow temperature graph.
Servo support
Supports industry-standard servos, so the oven door is automatically opened at the end of the reflow cycle.
J-STD-020 compliance
The Reflow Wizard is aware of the standards governing reflow ovens, and will auto-tune your oven so that it conforms to them.
